USGS Data Grapher Inventory Table

This utility allows the user to build an inventory table showing the number
or percentage of non-missing data points for the chosen site/parameter combination.
The same type of inventory table can be built for approved or provisional data.
Select the station, the parameter, the type of inventory table, and the starting
and ending dates. Then, click the button labeled "Make Table."

Note: I see that javascript is not currently enabled
in your browser. That's okay -- the Data Grapher will work without javascript.
I invite you to enable javascript for this page, however, because the
Data Grapher interface utilizes javascript to clarify and simplify data input.
